In this embodiment, the operation of determining the radio signal recommendation scheme based on whether the destination is set are described in more detail with reference toFIGS. 4-8 .FIGS. 4-8 are views illustrating a scheme of recommending a radio signal according to an embodiment of the present disclosure. - First, the
controller 230 may receive radio signal information received from thevehicle 100, broadcast channel information corresponding to the radio signal information, and information about whether the destination is set. Thecontroller 230 may determine whether the destination is set based on the information received from thevehicle 100. - When having determined that the destination is set (Y), the
controller 230 may determine to recommend a radio signal based on radio signal information corresponding to a road as the radio signal recommendation scheme. The road may include a highway (reference numeral 41 ofFIG. 4 ), a national road (reference numeral 51 ofFIG. 5 ), and a general road (reference numeral 61 ofFIG. 6 ). Thecontroller 230 may match route information generated corresponding to a destination setting on the road. Thecontroller 230 may recommend a radio signal corresponding to the road matched with the route information. In this embodiment, the radio signal corresponding to the road may be implemented with a road-based radio signal map. Thecontroller 230 may generate the road-based radio signal map by interconnecting a link classifying a road in units of a specified distance (1 km to 2 km) with a receivable radio signal. For example, when the route generated by the destination set by the user is generated on the highway and the general road, thecontroller 230 may recommend a radio signal interconnected with a link classifying the highway in units of a specified distance and a link classifying the general road in units of a specified distance. - Meanwhile, when having determined that the destination is not set (N), the
controller 230 may determine whether to recommend a radio signal based on radio signal information corresponding to a polygon area (reference numeral 71 ofFIG. 7 ). When thecontroller 230 determines that it is possible to recommend the radio signal based on the radio signal information corresponding to the polygon area (reference numeral 71 ofFIG. 7 ), thecontroller 230 may determine to recommend the radio signal based on the radio signal corresponding to the polygon area as the radio signal recommendation scheme. In this embodiment, thepolygon area 71 may include an area obtained by dividing a national map into a specified size. As shown inFIG. 7 , thepolygon area 71 may include a rectangle, but the embodiment is not limited thereto. Thepolygon area 71 may be implemented in various figures. The specified size may be 200 m to 400 m according to an embodiment of the present disclosure. The radio signal information corresponding to thepolygon area 71 may be implemented with a radio signal map based on thepolygon area 71. - The
controller 230 may generate the radio signal based on thepolygon area 71 interconnected with the radio signal receivable within thepolygon region 71. For example, when the user does not set a destination, thecontroller 230 may determine thepolygon area 71, in which the vehicle is currently located. Thecontroller 230 may recommend the radio signal interconnected with thepolygon area 71, in which the vehicle is located. - Meanwhile, when having determined that the radio signal cannot be recommended based on the radio signal information corresponding to the polygon area (
reference numeral 71 ofFIG. 7 ), thecontroller 230 may determine to recommend a radio signal based on radio signal corresponding to an administrative area (reference numeral 81 ofFIG. 8 ) as the radio signal recommendation scheme. In this embodiment, theadministrative area 81 may include a plurality of sections divided by the states in order to realize the public interest of the people. For example, theadministrative area 81 may be divided into units of cities, counties, and districts. In this embodiment, the radio signal information corresponding to theadministrative area 81 may be implemented as anadministrative area 81 based radio signal map. - The
controller 230 may generate theadministrative area 81 based radio signal map interconnected with the radio signal receivable within theadministrative area 81. For example, when the user does not set a destination and it is impossible to recommend a radio signal based on thepolygon area 71, thecontroller 230 may recommend the radio signal interconnected with theadministrative area 81, in which the vehicle is currently located. - The
controller 230 may generate the road-based radio signal map, the polygon area-based radio signal map, and the administrative area-based radio signal map based on the radio signal received at the location of the vehicle. The maps are used when recommending the radio signal as the radio signal recommendation scheme determined based on whether the destination is set. - First, the
controller 230 receives the vehicle information. In this embodiment, the vehicle information may include the location of the vehicle (GPS coordinates, administrative area code), the time, the vehicle speed, the strength of the radio signal being received, and the radio signal strengths of all channels. Thecontroller 230 may collect a radio signal received for each vehicle location and match the collected radio signal with a broadcast channel. In other words, the broadcast channel corresponding to the received radio signal may be identified by matching the radio signal received for each vehicle location with the corresponding broadcast channel. Thecontroller 230 determines whether to store the received radio signal according to whether the current weather condition is clear when having determined that the vehicle is located in a new visited area, where there has never been a previous visit history. In other words, thecontroller 230 may store the radio signal when the current weather is clear and a signal reception state is normal. In this embodiment, the new visited area may be classified into at least one of a road, a polygon area, and an administrative area. Meanwhile, thecontroller 230 may re-receive the vehicle information when the signal reception state is poor because the current weather is not clear. - When the radio signal is recommended based on the recommendation method determined based on whether the destination is set, the
controller 230 may determine whether the recommended radio signal is applicable. In an embodiment, thecontroller 230 may determine that the recommended radio signal is applicable when the broadcast channel corresponding to the recommended radio signal is the same as the broadcast channel corresponding to the radio signal received by thevehicle 100. Thecontroller 230 may identify the broadcast channel corresponding to the radio signal received by thevehicle 100 based on the information received from thevehicle 100. - When the
controller 230 determines that the broadcast channel corresponding to the recommended radio signal is the same as the broadcast channel corresponding to the radio signal being received by thevehicle 100, thecontroller 230 may determine that the recommended radio signal is applicable. Thecontroller 230 may generate a radio recommendation list based on the recommended radio signal. However, when the broadcast channel corresponding to the recommended radio signal is different from the broadcast channel corresponding to the radio signal received by the vehicle, thecontroller 230 may generate a radio signal recommendation list based on a personal propensity. In this embodiment, when the broadcast channel corresponding to the recommended radio signal and the broadcast channel corresponding to the radio signal received from the vehicle are not the same, the broadcast channel corresponding to the recommended radio signal is broadcasted only in the area where the vehicle is currently located. Thus, the broadcast channel may be a broadcast channel not broadcasted in the area where the vehicle is receiving the radio signal. In another embodiment, the broadcast channel corresponding to the received radio signal may not be broadcasted in the area where the vehicle is located (or an area where the vehicle is located). - The
controller 230 may generate the radio signal recommendation list based on a user propensity. The user propensity may be set based on a radio signal received by a user. In an embodiment, thecontroller 230 collects a radio signal received by a user and matches the collected information-based broadcast channel. Thecontroller 230 may receive program information based on the program information of the broadcast channel. Thecontroller 230 may set the user propensity based on the program information corresponding to the radio signal received by the user based on the received program information. For example, when having determined that the radio signal received by the user is receiving the latest pop music program of frequency ‘A’, thecontroller 230 may determine that the user prefers the latest pop music listening. - The
controller 230 may generate the radio signal recommendation list based on the user propensity set as described above. For example, when having determined that the user prefers the latest pop music listening, thecontroller 230 may generate a radio signal recommendation list based on a radio signal of a broadcast channel through which the latest pop music is broadcasted. - When the reception of the radio signal broadcasting the latest pop music is not easy, the
controller 230 may generate a radio signal recommendation list based on a radio signal that can be received based on a user listening history or based on a real-time listening rate rank at the current location of the vehicle. - In addition, when the radio signal recommendation list is generated, the
controller 230 may control to transmit the radio signal recommendation list to thevehicle 100. -
FIG. 9 is a flowchart illustrating an operation of a vehicle according to an embodiment of the present disclosure. - As shown in
FIG. 9 , in operation S110, thecontroller 160 receives a radio signal. In operation S120, thecontroller 160 matches the radio signal received in operation S110 with a broadcast channel. - In operation S130, the
controller 160 determines whether a strength of the radio signal being received is less than a specified value. When having determined in operation S130 that the received radio signal is less than a specified value (Y), in operation S140, thecontroller 160 determines whether a destination is set. Meanwhile, when having determined in operation S130 that the received radio signal is greater than or equal to the specified value (N), in operation S110, thecontroller 160 receives the radio signal. - When having determined in operation S140 that the destination is set, in operation S150, the
controller 160 transmits, to theserver 200, the radio signal information received in operation S110, the broadcast channel information matched in operation S120, and the set destination setting information. Meanwhile, when having determined in operation S140 that the destination is not set, in operation S160, thecontroller 160 transmits, to theserver 200, the radio signal information received in operation S110, the broadcast channel information matched in operation S120, and the current location information. - The
controller 160 receives the radio signal recommendation list from the server 200 (S170). Thecontroller 160 determines whether the recommended radio signal strength exceeds the currently received radio signal strength (S180). When having determined in operation S180 that the recommended radio signal strength exceeds the currently received radio signal strength (Y), in operation S190, thecontroller 160 receives the recommended radio signal. When having determined in operation S180 that the recommended radio signal strength is less than or equal to the currently received radio signal strength (N), thecontroller 160 performs an operation S170. -
FIG. 10 is a flowchart illustrating an operation of a server according to an embodiment of the present disclosure. - As shown in
FIG. 10 , in operation S210, thecontroller 230 receives radio signal information currently received from thevehicle 100, matched broadcast channel information, destination setting information when the destination setting information exists, and current location information of the vehicle when there is no destination setting information. In operation S220, thecontroller 230 determines whether the destination setting information is received from thevehicle 100 in operation S210. When the destination setting information is received in operation S220 (Y), thecontroller 230 recommends a radio signal based on the radio signal information corresponding to a road information in operation S230. The radio signal information corresponding to the road information in operation S230 may be implemented with a road-based radio signal map. Thecontroller 230 may generate the road-based radio signal map by interconnecting a link of classifying a road in units of a specified distance (1 km to 2 km) with the receivable radio signal. For example, when the route generated by the destination set by the user is generated on a highway and a general road, thecontroller 230 may recommend a radio signal interconnected with a link of classifying the highway in units of a specified distance and a link of classifying the general road in units of a specified distance. - Meanwhile, when having determined in operation S220 that the
controller 230 does not receive the destination information (N), in operation S240, thecontroller 230 may determine whether to recommend a radio signal based on radio signal information corresponding to a polygon area. - When having determined in operation S240 that it is possible to recommend a radio signal based on the radio signal information corresponding to the polygon region (Y), in operation S260, the
controller 230 recommends the radio signal based on the radio signal corresponding to the polygon area. In this embodiment, the radio signal information corresponding to the polygon area may be implemented with a polygon area-based radio signal map. Thecontroller 230 may generate the polygon area-based radio signal map interconnected with the radio signal receivable in one polygon area. For example, when the user does not set a destination, in operation S260, thecontroller 230 determines the polygon area, in which the vehicle is currently located. Thecontroller 230 recommends the radio signal interconnected with thepolygon area 71, in which the vehicle is located. - When having determined in operation S240 that it is impossible to recommend the radio signal based on the radio signal information corresponding to the polygon area (N), in operation S250, the
controller 230 recommends a radio signal based on the radio signal corresponding to an administrative area. In this embodiment, the radio signal information corresponding to the administrative area may be implemented as an administrative area-based radio signal. The administrative area-based radio signal map may be generated in interconnection with a radio signal receivable in one administrative area. For example, when the user does not set a destination and it is impossible to recommend a radio signal based on a polygon area, thecontroller 230 may recommend a radio signal interconnected with the administrative area, where a vehicle is currently located. - In operation S270, the
controller 230 determines whether the radio signals recommended in operations S230, S260 and S250 are applicable. When having determined in operation S270 that the broadcast channel corresponding to the recommended radio signal is the same as the broadcast channel corresponding to the radio signal received by the vehicle, in operation S280, thecontroller 230 determines that the radio signals recommended in operations S230, S260 and S250 are applicable (Y). Thecontroller 230 generates a radio signal recommendation list based on the recommended radio signals. - When having determined in operation S270 that the broadcast channel corresponding to the recommended radio signal and the broadcast channel of the radio signal received by the vehicle are not the same, in operation S290, the
controller 230 determines that it is impossible to apply the radio signals recommended in operations S230, S250 and S260 (N). Thecontroller 230 generates a radio signal recommendation list based on a user propensity. The operation of setting a user propensity in operation S290 are described with reference toFIG. 12 . - In operation S290, when having determined that a user prefers the latest pop music listening, the
controller 230 may generate a radio signal recommendation list based on a radio signal of the broadcast channel through which the latest pop music is broadcasted. However, when it is not easy to receive the radio signal currently broadcasting the latest pop music, thecontroller 230 may generate a radio signal recommendation list based on a currently receivable radio signal and the user listening history or based on a real-time listening rate ranking at the current location of the vehicle. - When the radio signal recommendation list is generated in operations S280 to S290, in operation S300, the
controller 230 transmits the radio signal recommendation list to thevehicle 100. -
FIG. 11 is a flowchart illustrating a method of updating radio signal map information according to an embodiment of the present disclosure. - As illustrated in
FIG. 11 , thecontroller 230 receives the information about the vehicle in operation S310. The vehicle information in operation S310 may include the location of the vehicle (GPS coordinates, administrative area code), the time, the vehicle speed, the strength of the radio signal being received, and the radio signal strengths of all channels. - The
controller 230 may collect a radio signal received for each vehicle position in operation S320 and match the collected radio signal with a broadcast channel in operation S330. In operations S320 and S330, thecontroller 230 may identify the broadcast channel corresponding to the received radio signal by matching the broadcast channel with the radio signal received for each vehicle position. - The
controller 230 determines whether the location of the vehicle is a new visited area without a previous visit history in operation S340. When having determined in operation S340 that the location of the vehicle is a new visited area without a previous visit history (Y), thecontroller 230 determines whether the current weather condition is clear in operation S350. The receiving rate of the radio signal is different according to the weather condition. Thus, the determining whether the weather condition is clear by thecontroller 230 in operation S350 is for the purpose of determining whether it is easy to receive a radio signal. When having determined in operation S350 that the current weather is clear and the signal reception state is normal, in operation S360, thecontroller 230 stores the radio signal information corresponding to the new visited area. In operation S360, the new visited area may be classified into at least one of a road, a polygon area, and an administrative area. Meanwhile, when the current location is not a new visited area (N) in operation S340, or the reception state is not normal because the current weather is not clear in operation S350, thecontroller 230 performs an operation S310 to re-receive the vehicle information. -
FIG. 12 is a flowchart illustrating a method for storing personal propensity information according to an embodiment of the present disclosure. - As illustrated in
FIG. 12 , thecontroller 230 collects a radio signal received by the user in operation S410. In operation S420, thecontroller 230 matches a broadcast channel based on the radio signal information collected in S410. In operation S430, thecontroller 230 receives program information in the broadcast channel matched in operation S420. In operation S440, thecontroller 230 identifies the program corresponding to the received radio signal. In operation S450, thecontroller 230 may set a user propensity based on the identified program information. For example, when the identified program information is the latest pop music program in operation S440, thecontroller 230 may determine that the user prefers the latest pop music listening and may set the preferred genre as the user propensity. -
